Since the sum of the angles of a triangle = 180°
Then <span>80º + (2x + 2)º + 5xº = 180</span>°
82° + (7x)° = 180°
(7x)° = 180° - 82°
x = 98° ÷ 7
∴ x = 14
the answer its 12.5% i swer its ok and hope helps you
Combine like terms. Remember that like terms are terms that are completely the same excluding the coefficient.
7x-8x=-1x
Final answer: -x+5
